LinkedList.java

// Certainly! Here's an example of a basic implementation of a singly linked list in Java:

// ```java

import java.util.Queue;

class Node {
    int data;
    Node next;

    public Node(int data) {
        this.data = data;
        this.next = null;
    }
}

class LinkedList implements Queue<Integer> {
    Node head;

    public LinkedList() {
        this.head = null;
    }

    // Method to insert a new node at the end of the linked list
    public void insert(int data) {
        Node newNode = new Node(data);
        if (head == null) {
            head = newNode;
        } else {
            Node current = head;
            while (current.next != null) {
                current = current.next;
            }
            current.next = newNode;
        }
    }

    // Method to display the linked list
    public void display() {
        Node current = head;
        while (current != null) {
            System.out.print(current.data + " ");
            current = current.next;
        }
        System.out.println();
    }
    
    public static void main(String[] args) {
        LinkedList list = new LinkedList();

        // Inserting elements into the linked list
        list.insert(1);
        list.insert(2);
        list.insert(3);
        list.insert(4);

        // Displaying the linked list
        System.out.println("Linked List:");
        list.display();
    }
    
}
// ```

// This code defines a `Node` class to represent each element in the linked list and a `LinkedList` class to manage the list. The `insert` method adds elements to the end of the list, and the `display` method prints the elements in the list.

// You can run this code and modify it as needed to perform other operations like deletion, insertion at a specific position, or any other functionality you require in a linked list.
